A control valve arrangement (10) for stacker trucks is proposed which serves to control two consumers in parallel at different pressure levels. It comprises at least two directional control valves (14, 15) in double-flow construction, from which, downstream of the latter valve, a circulation passage (26) allocated to the first flow and a distribution passage (25) allocated to the second flow are brought together via a first transverse connection (51). From there (51), a second transverse connection (56) leads via an additional directional control valve (12) in single-flow construction to the second circulation passage (27) upstream of the directional control valves in double-flow construction and further via these directional control valves to the tank (34). In this way, simple, standard directional control valves (12) in single-flow construction can be combined with directional control valves (14, 15) in double-flow construction and can control flows of different magnitude. In addition, different pressure protection measures can be carried out for both flows. <IMAGE>
